Soccer Odds: A guide to how bookmaker odds work
Date: Sunday, 1st Sep 2024Did you know that on average, more than 1 billion bets are taken on a single English Premier League soccer match from all over the world?
For endless years, soccer has been one of the most sought-after sports disciplines for betting, attracting millions of enthusiasts and professional punters on specialized betting sites and even some casino non uk.
However, behind the seeming simplicity of betting on the outcome of a match lies a whole science - betting odds. The ability to read and interpret odds correctly can be the key to success for any player, whether he is a beginner or an experienced bettor. Today we will dive into the depths of bookmaker odds, reveal the secrets of their formation and share strategies that will help to maximize the benefits of your bets on soccer.
A minute of theory and basic information about bookmaker odds
Bookmaker odds are numbers assigned by bookmakers to each possible outcome of an event. They reflect the probability of an outcome and determine the size of the potential payout in the event of a successful bet. The lower the odds, the higher the probability of the event according to the bookmaker, and vice versa. There are three main types of odds used in the world of sports betting:- Fractional
- Decimal (European)
- Money Line (American)
Each format has its own peculiarities and preferences in different countries and bookmaker`s offices.
Fractional. Fractional odds are traditionally used in the UK and countries that were formerly part of the British Empire. They are represented as a fraction, for example, 4/1 or 5/2. The numerator shows the size of the potential winnings and the denominator shows the amount of the bet. Thus, the ratio 4/1 means that with a bet of 1 conventional unit, the winnings will amount to 4 units. Accordingly, the total payout will be equal to 5 units (4 winnings + 1 bet).
Decimal. This format of odds is widely spread in Europe and CIS countries. They are specified as a decimal fraction, for example, 3.30 or 2.85. To calculate the winnings you need to multiply the amount of the bet by the coefficient. If you bet 10 conventional units on odds of 3.30, your potential winnings will be 33 c.u. (10 x 3.30).
Money Line (American). Money Line is a format used primarily in the United States and Canada. It is based on a $100 bet and is indicated with a plus or minus number. A positive number indicates the potential winnings for a $100 bet, while a negative number indicates the amount you need to bet to win $100. For example, a +180 odds means you can win $180 with a $100 bet, while a -210 odds requires a bet of $210 to win $100.
Regardless of the format, all odds reflect the same probability of an event. To illustrate, odds of 2.00 in European format are equivalent to 1/1 in fractional and -100 in Money Line.
This means that there is a 50% probability of the event happening, and if the event is successful you will double your original bet. You can see more information about the different types of sports betting here.
It is also important to keep in mind the immutable truth - modern bookmakers set the odds in such a way as to provide themselves with a mathematical advantage called margin. This means that the sum of the inverse probabilities of all possible outcomes of an event exceeds one.
Again, to illustrate: if a bookmaker puts in the line odds of 2.00 for a victory of team A and 2.00 for a sports victory of team B, the sum of inverse probabilities will be 1 (1/2 + 1/2 = 1). In practice, however, the numbers from the bookmaker may be 1.90 and 1.90, giving a sum of 1.05 (1/1.90 + 1/1.90 = 1.05). This difference of 0.05 (or 5%) is the bookmaker`s margin, which guarantees a profit on the long-term planning horizon.
How bookmakers set their odds
Setting odds by a bookmaker is a complex process that requires in-depth analysis of many factors. Bookmakers use the services of professional analysts and traders who thoroughly study all available data and statistics to assess the probability of each possible outcome of an event as accurately as possible.
Factors influencing the formation of odds
Modern bookmakers rely on several significant factors at once when forming the actual line of odds. Here are the main ones:
- Team form - bookmaker analysts analyze the results of recent matches, goals scored and conceded, game discipline and other indicators to determine the current level of form of each team. Teams with consistently high results receive lower odds to win, while outsiders have higher odds.
- Injuries and suspensions of players - the loss of key players can seriously weaken a team and reduce its chances of success. Bookmakers closely monitor information about the teams` lineups and adjust the odds accordingly.
- Home field is another important factor. Statistics show that teams playing in their own stadium have an advantage over guests. This is due to the support of fans, familiar conditions and no need to move. Therefore, bookmakers, as a rule, offer lower odds on the victory of the home team.
- Weather conditions and the state of the pitch - rain, snow or strong wind can create additional difficulties for the players and change the nature of the game. Bookmakers analyze weather forecasts and pitch conditions to adjust their estimates.
- Bookmakers constantly monitor the flow of money - the volume and direction of punters` bets. If there is a significant flow of bets on a certain outcome, bookmakers may revise their odds to balance the betting line and minimize risks.
Bookmakers` analysts also take into account the history of confrontations between teams, the current tournament situation, players` motivation and coaching staff. For example, in the decisive matches of the season or when fighting for the championship, teams can demonstrate higher motivation and concentration, which is reflected in the odds.
All these factors are carefully studied and analyzed by teams of betting experts. They use advanced statistical models, algorithms and software to process huge data sets and identify the most likely scenarios. It is on the basis of these calculations that bookmaker odds are formed, which are then offered to sports fans and gamblers.
The role of the bookmaker`s margin
Bookmaker`s offices are commercial enterprises whose main goal is to make a profit. To achieve this goal, they use the so-called margin - a mathematical advantage embedded in the odds. Accordingly, the bookmaker`s margin is the difference between the real probability of the event and the probability reflected in the odds. This numerical difference forms a guaranteed profit for bookmakers in the long term, regardless of the outcome of events.
To better understand the concept of margin, let`s consider a simple example. Suppose a bookmaker offers the following odds for a match between teams A and B:
- Team A`s victory - 2.00.
- Victory of team B - 2.00.
If we translate these odds into probabilities, we get:
- Team A`s probability of winning = 1 / 2.00 = 0.50 or 50%.
- The probability of victory of team B = 1 / 2.00 = 0.50 or 50%.
The sum of these probabilities is equal to 1 or 100%, which corresponds to the real situation when one of the two outcomes is bound to happen. However, in practice bookmakers never set the odds in this way.
Instead, they lower the odds so that the sum of the inverse probabilities exceeds 1. For example:
- Team A`s victory - 1.90.
- Team B`s win is 1.90.
In this case, the probability of Team A winning = 1 / 1.90 = 0.526 or 52.6%, and the probability of Team B winning = 1 / 1.90 = 0.526 or 52.6%. The sum of the probabilities is 1.052 or 105.2%, which exceeds 100% by 5.2%. This difference of 5.2% is the bookmaker`s margin.
The higher the margin, the greater the bookmaker`s advantage and the lower the probability of winning for punters in the long run. The typical margin in soccer is between 5% and 10%, although in some cases it can be higher or lower depending on the specific event and the bookmaker`s strategy.
Margin applies not only to two-goal events, but also to bets on totals, forfeits, exact scores and other markets. Bookmakers carefully calculate the margin for each market to ensure that they have a mathematical advantage regardless of the outcome of the event.
Odds change depending on the player`s bets
Bookmaker odds are not static values - they are constantly changing depending on various factors, one of which is the activity of players and the direction of their bets. Bookmakers strive to balance their betting line to minimize risks and guarantee profit regardless of the outcome of the event. To do this, they closely monitor the movement of money - the volume and direction of players` bets on different outcomes.
If a certain outcome receives significantly more bets than others, the bookmaker may reduce the odds on this outcome to make it less attractive to players and balance the betting line. Accordingly, the odds on less popular outcomes will be increased to attract more bets.
For example, before a match between teams A and B, a bookmaker may place the following odds:
- Team A victory - 2.00.
- Draw - 3.50.
- Victory of team B - 4.00.
If the majority of players start to actively bet on the victory of team A, the bookmaker can reduce the odds on this outcome, for example, to 1.75, and at the same time increase the odds on other outcomes to balance the betting line. Odds change in real time, and bookmakers use specialized software and teams of traders to constantly monitor and adjust the odds.
In addition to the movement of money, bookmakers also take into account other factors that affect changes in the odds. For example, if an injury to a key player of one of the teams becomes known a few hours before the match, this can lead to a significant change in the odds. Odds can also change during the match itself, reflecting the current situation on the field. If one of the teams opens the scoring or remains in the minority due to the removal of a player, bookmakers quickly adjust the odds to reflect the new realities.
It is important to keep in mind that changing the odds does not always mean the bookmaker`s desire to gain an advantage over the players. On the contrary, it is a necessary measure to manage risks and provide a balanced betting line. Experienced punters closely monitor the movement of odds and use this information to make more informed decisions. A sudden change in the odds may indicate that bookmakers have certain information that is not available to the general public.
Soccer betting strategies based on odds
Understanding bookmaker odds and the factors that influence their formation opens up a wide range of strategies for successful soccer betting. Armed with this knowledge, the bettor can more effectively analyze the offered odds and find potentially profitable bets. Here are a few common strategies.
Betting on favorites and underdogs
One of the most common strategies is based on finding over- or under-valued odds on favorites and underdogs. Bookmakers are often too cautious in assessing the chances of the clear favorites, offering relatively high odds on them. On the other hand, the odds on underdogs may be underestimated due to underestimating their chances.
Experienced players carefully analyze pre-match statistics, team form, injuries and other factors to identify such discrepancies. If their own estimate of the probability of the favorite winning is higher than reflected in the odds, it can be a profitable bet. Similarly, inflated odds on underdogs can be of interest if there are good reasons for their success.
Finding “forks”
Forks are situations where the odds on the same event at different bookmakers diverge so much that a player can make a guaranteed profit regardless of the outcome. Forks are rare and are quickly closed by bookmakers, but finding and using them can be a profitable strategy for experienced players.
System Betting Strategy
System betting is placing multiple bets on the same event with different combinations of outcomes. The most popular system is the “double chance” strategy, when a player bets on two outcomes out of three possible outcomes (home team victory, draw, guest victory). This strategy reduces the risk of losing, but also reduces the potential winnings due to the lower odds on the combined outcomes. Players carefully analyze the odds to determine if they compensate for the additional risks.
Betting on totals and odds
In addition to betting on match outcomes, odds are also offered on totals (the number of goals scored in a match) and forfeits (a predetermined scoreline). These markets can present interesting betting opportunities, especially when bookmakers misjudge the attacking or defensive potential of teams.
For example, if two attacking teams meet, but the bookmaker offers low odds for a total of more than 2.5 goals, it can be an attractive bet. Or if one of the teams is a clear favorite, but the odds on its head-to-head (-1.5) are too high, it can also be a profitable betting situation. Players study the statistics of goals scored and conceded, the current form of the teams, their motivation and other factors to estimate the probability of various totals and forfeits. They then compare their estimates with the offered odds and find potentially profitable bets.
It is important to note that none of these strategies guarantee one hundred percent success. Betting on sports always involves risks, and even the most careful calculations can be overturned by the unpredictability of soccer matches. However, a competent analysis of odds combined with in-depth knowledge of soccer and a disciplined approach to bankroll management can significantly increase the chances of long-term profit.
Successful players are constantly improving their strategies, adapting to changes in the market and utilizing various sources of information to gain an advantage over bookmakers. Odds are a key tool in this process, allowing you to identify valuable bets and make informed decisions.
The basics of risk management in soccer betting
Risk management is a key aspect of successful soccer betting. Even experienced punters can lose all their money due to poor bankroll management. Here are some important principles that will help you control your risks and protect your bankroll:
-Set reasonable betting limits - never bet more than you can afford to lose. A good tip is to bet no more than 1-3% of your total bankroll on a single prediction. This will help you avoid catastrophic losses due to a few bad bets.
-Diversify your bets - don`t just focus on one league or type of bet. Spread your investment across different tournaments, leagues and betting types. This will reduce the risk of loss when a series of bets goes awry.
-Use a fixed betting system - determine a fixed amount for each type of bet and stick to it. Do not increase the size of the bet in an attempt to win back after a series of losses. After all, this is an extremely dangerous strategy that often leads to even more losses.
-Consider odds when assessing risk - bets with high odds have the potential to be more profitable, but they also carry a higher risk. Carefully analyze the likelihood of an event happening before placing large bets at high odds.
-Keep a record of your bets -keep track of each bet, the outcome and the reasons for success or failure. This will help you identify weaknesses in your strategy and areas for improvement.
Following sound risk management is a must for long-term success in soccer betting. Control your bets, diversify your risks and never bet more than you can afford to lose. Stick to these principles and you will be able to enjoy the exciting world of soccer betting without putting your bankroll at excessive risk.
